To be honest, front closure bras work well for any frame. But I find the benefits extend further for larger busted or plus size ladies. This is for a few reasons. Firstly, they can be much easier to get in to. Because of this the brands can then build them with stronger fabrics which is a great thing for supporting heavier breasts and also adding to the lifespan on the bra. Secondly, front closure plus size bras often have a full back design which helps to leave a smooth line on the back and also helps to redistribute the weight of a heavy bust on to the back. Those are really neat features.
